Aircraft design expert witnesses may report on the airline industry, aviation accident analysis, aviation safety, the aircraft industry and associated matters. In the news, Boeing 787 Dreamliners are grounded around the globe for safety checks. Aviation experts say that fires on two 787 aircraft were likely caused by lithium-ion batteries receiving too much voltage too quickly. Dr. Jay Whitacre, Associate Professor at the Department of Materials Science and Engineering, Carnegie Mellon University, states “Other batteries don’t go this wrong when you treat them this badly.” Professor Whitacre has worked on developing a materials system for energy storage technologies at the Jet Propulsion Laboratory and was a member of the Mars Science Laboratory development team.
